IMPROVEMENT IN STOP-MOTIONS FOR WINDING-FRAMES.

Specification forming part of Letters Patent No.- 124,989, dated March 26, 1872.

To all whom it may concern:

Be it known that we, THo uAs UNSWORTH and EDWARD WHALLEY, of Manchester, England, have invented a new Improved Self- StoppingWinding-Frame, and we do hereby declare the following, when taken in connection with the accompanying drawing and the letters of referencemarkedthereon, to be a full, clear, and exact description of the same, and which said drawing constitutes a part of this specification.

Figure 1 is a front elevation. Fig. 2 is an end view of that end marked 1. Fig. 3 is likewise an end view of that end marked 2. Fig. 4 is a plan of the whole.

Our invention consists of a susceptible mechanical arrangement for stopping the bobbins in a winding-frame when a thread breaks.

We know that a patent was granted in En gland to Robert Smith, of Manchester, England, on the 28th day of March, 1870, for a machine, professedly, for the same purpose. This ma chine, when an end breaks, allows the bobbin to run several times round before it stops, causing the winder to lose much time in getting the ends to piece up. In our invention, instantly a thread breaks the bobbin on which it is being wound stops, leaving the ends in sight of the winder, without having to search and unwind the bobbin to recover it.

A, in Figs. 1, 2, and 3, are the cops or equivalent, from which we draw our threads. B, dotted in Figs. 2 and 3, is a cross-bar, which we cover with flannel of a brush or equivalent. (l (l are slit plates to take the snioks out of the yarn. D l) are breastboards, over which the threads pass to eyelets a in the ends of levers E. These levers are fulcrumed to stands F by bar G. On the other ends of these levers E rest bar'H. This bar goes through and is secured to lever I, which lever is ful crumed to stand-brackets J, Fig. 4, which stand behind stand-bracket b, in Figs. 2 and 3. This lever I has a step-leg, K, on Fig. 2, on which rests the bow end of another fulcrum-lever, M, which fulcrums onto headstock N of driven shaft 0. The end of this lever is of a catch-tooth shape, as at p in Fig. 2, and

fits the catch-wheel P. On the side of such catch-wheel is a friction-roller, R, fixed on spindle S, on which are bobbins T, on which the threads are wound. Immediately under the friction-roller It, and on the driven shaft 0, is another friction-roller, U, (on Fig. 2,) which drives the upper friction-roller R, and by spindles S, bobbins T. The whole is driven by pulley W, through shaft V and wheels X, Y, and Z. I) b are stands carryinga rod, 0, over which the threads pass to bobbins T. There is an ordinary regulating traverse-lever, d, on which, and in front of each bobbin, is a threelegged guide, h, which bands the threads to gether and carries them regularly from end to end of bobbins, so astdkeep it evenly wound. This lever is WDIked by aheart-sha-ped cam,

e, by pivots f, whichgets' its action from driven shaft 0, by and through screw 9 and screwwheel 41, in Figs. 2 and 4..

We regulate the traverse by slot-lever in the center of the machine. Its action is as follows: The several threads of yarn or other material to be Wound passes from cops A round cross-bar B, through slit plate 0, over breastboard D, through eyelets a in the ends of levers E, over rod 0, through guide-legs h, to bobbins T. t is a check-bar, to prevent levers E from shaking off or getting outof position.

The levers E, with the bars H resting on the short ends, are kept up to their position by all the threads passing through the eyelets a, and are so balanced that when one thread breaks the eyelet end of such lever falls and lifts up bar Hand that end of lever I, which has the effect of backing out K end of such lever, when lever L end drops down, lifting the other or tooth-end up, which slips into catch wheel 1? and instantly stops bobbins T, which are on the same spindle S, and'remains so stopped until such broken thread is pieced and bobbin replaced in its proper position.

The heart-cam traverse motion keeps the regulating-lever always moving regularly from end to end of bobbins.

Having fully described our invention, we may remark, in conclusion, that, independent of its other advantages, we can wiudmuch tighter, and put a considerable percentage of the first clause of claim, we claim the catchmore yarn on the same sized bobbin than by wheel P, friction-rollersR and U, substantially any other process hitherto known. as hereinbefore set forth.

we claim as our invention THOMAS UNSWORTH. 1. The levers E, I, and M, in combination, EDWARD WHALLEY. substantially as and for the purpose hereinbe- Witnesses: fore set forth. JOHN LEWIS,
